Turkey must reckon with Azerbaijan, Leader of the Turkish opposition Republican People's Party (RPP), Deniz Baykal said at the meeting, CNN Turk reported.
"Turkey is obliged to reckon with Azerbaijan," said Baykal.
Turkish and Armenian Foreign Ministers, Ahmet Davutoglu and Edward Nalbandian signed the Ankara-Yerevan protocol in Zurich on Oct. 10.
Armenian-Turkish ties have been severed since 1993 due to Armenia's claims of an alleged genocide, and the country's occupation of 20 percent of Azerbaijani lands.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied 20 percent of Azerbaijan since 1992, including the Nagorno-Karabakh region and 7 surrounding districts. Azerbaijan and Armenia signed a ceasefire agreement in 1994. The co-chairs of the OSCE Minsk Group - Russia, France, and the U.S. - are currently holding the peace negotiations
Baykal also said that although his party called on the Turkish authorities not to sign the protocol with Armenia, their words were not accepted seriously.
He said this process serves to separate Azerbaijan from Turkey.
"PKK terrorists by surrendering crossed the border with their flags in their hands, but unfortunately, the Azerbaijani flags were not allowed to the Armenia-Turkey football match," said Baykal.
"The government does not have enough power to the PKK, but to Azerbaijan," he said.
He said the Azerbaijani-Turkish relations are also experiencing a bitter situation. "Show me a country whose brother is in a state of war and killed, but they would shake hands with its enemies," said the leader of the PRR.
According to Baykal, the Turkish-Azerbaijani brotherly ties should not become a victim of the Turkish government's mistakes.
